Saint Bernard STILL MISSING!! Palouse

My father-in-law's Saint Bernard named Opie has been missing from their home on the outskirts of town in Palouse, Wash., (State Route 272 and Swanson Road) since sometime Monday, Dec. 17. He was there when they went to work Monday morning and gone when they got home in the evening. It is not normal for him not stick around on their property as they have had him since 2014. He is an old Saint Bernard, probably around 10 or so in age.
